SHOE-UPPER-POUNDING MACHINE.

Specification of Letters Patent.

Application tiled April 30,1906. Serial No. 314,439.

To (.LM whom it may concern.-

Be it known that I, SAMUEL J. \rVENT- WORTH, a citizen of the United States, residing at Newport, in the county of Campbell under the spindle 3. It has at its rear end a pin 15, which projects through the slot 16. through the stock. (See dotted lines, Fig. 1.)

' On the front end ol? the rod 14 is a bracket and State of Kentucky, have invented cer' 17, in the front end of which is journaled a roller 18.

19 represents a coilspring around rod 14 between the bracket 17 and the front end of the st-oc k 2.

in operation the shoe is presented to the l'acedl) ol' the hanuner,'the opera-tor pressing It is the object of the invention to produce a cheap and simple device adapted to impart a rapid hammering action around the heel, vamp, and toe of the lasted upper.

The features of the invention will be more fully set forth-in the-description of the accompanying drawings, forming a part of this specification, in which V Figure l is a central vertical section of my lmproved device.

Fig, 2 is a front elevation of the upper or pounding portion of the maj chine. Fig. 4 is a top plan view of the same.

1 represents a standard having a head stock 2, in which is journaled a spindle 3, held in position by a key 4, engaging into the elongated notch 5 on spindle 3. The hearing of the stock 2 has an enlarged bore 6 in one end.

7 represents a collar on the front end oi 'the spindle 3.

8 represents a coil-spring on the spindle between the collar 7 and the rear wall of-the bore 6. it will thus be seen that the spindle is adapted to receive a horizontal vibratory motion in its bearing, the stroke of which is fixed by the length of the notch end of the spindle 3 is a hammer 9, having a concave face 10, forming a suitable bearing l'or the edge of the shoe-upper whichis to be presented thereto. The rear end of the spindle 3 projects beyond the stock 2 and is provided with the antifrictien-roll ll.

l2r n resents a shalt to which is iixed the cams 1Z5.

14: represents a rod j ournaled in the stock 2 big. 3 is a rear elevation thereof. f position indicated in Fig. 4 n iront of the On the 5 inward, compressing the spring 6- and presenting the roll 11 tothe action of the rapidlyrevolvmg cams l3. As each cam strikes the roll it throws the spindle forward, and so a rapid hammering or vibrating action is im parted to the spindle, which is resisted by the shoe held under pressure by the operator to the iulluencc of the hammer. When the sides ol the upper are under operation, the roll 15 is pressed back ilush with the face of i the hammer; but when the heel or toe is turned around over the hammer it lies above tlus roller, and the roller comes out in the hammer and serves as a "rude to the 0 erator, so that he can keep the heel on the hammer.

Having described my invention, 1 claim in an upper-pounding machine, a stock, a spindle extended through the stock and projecting beyond the sa ine at opposite ends, nn'aans permitting the spindle to be reciprocated in the stock, a hammer on the front end of the stock, a cam device in rear of the spindle normally out of contact therewith but adapted to engage the same when the spindle is pressed inward, and a spring-controlled guide under the hamnmr and in front thereof normally, but adapted to retreat under pressure independent of the hammer, substantially as described.

In testimony whereof I have hereunto set my hand.
